Transform your DeWalt woodworking kit into a professional-grade cutting system with our precision-engineered spiral cutterhead upgrades. Designed specifically for DeWalt DW735, DW735X, DW735-XE thickness planers and DCP580 cordless planers, our collection delivers exceptional performance that revolutionizes how you work with wood.
Each expertly manufactured cutter head represents a dramatic improvement over traditional straight-knife systems. Our OEM-diameter helical design features 40 to 56 premium tungsten carbide inserts arranged in optimized 4-row spiral configurations, creating superior shear-cutting action that eliminates tear-out on birdseye maple, curly maple, oak, and other challenging figured hardwoods while producing glass-smooth finishes.
These precision-crafted mechanical components are built with black oxide coating for superior rust protection and come with pre-installed premium Japanese NSK bearings—saving 30 minutes of installation time. Our spiral cutterhead jointer technology delivers whisper-quiet operation, reducing noise levels by over 50% while improving dust collection efficiency through smaller chip production.
The tungsten carbide inserts in these advanced woodworking tools maintain exceptional cutting performance up to 50 times longer than high-speed steel blades. Each insert features four indexable cutting edges with radius-corner design—simply rotate for a fresh edge without complex alignment or blade sharpening. This innovative indexed system guarantees perfect knife placement every time, eliminating the time-consuming precision work required by stock three-knife cutterheads.
Manufactured with high-tensile alloy steel construction, dynamically balanced for smooth operation, and backed by comprehensive warranty coverage, our DeWalt woodworking kit spiral cutterheads represent a smart investment that pays for itself quickly. Experience dramatically reduced tear-out, virtually eliminated sanding work, and professional-grade results with every pass—transforming your DeWalt planer into a precision cutting powerhouse that handles hardwoods and softwoods with equal excellence.
Do I need to replace the original bearings?
If the bearings in your machine are in good condition, they can be reused by carefully removing them with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removal may cause damage. To minimize this risk, we recommend replacing old bearings with our greased and sealed bearings, designed for long-lasting performance. For a smooth upgrade, we suggest adding the bearings to your shopping cart before completing your purchase.
We provide premium bearings from NSK, SKF, NTN, FAG, Timken. They are renowned for their high quality and performance, designed to provide durability and reliability in various applications
Do I need to to Add a Few Boxes of Carbide Inserts
We provide 5 carbide inserts and 5 screws as spare parts. However, many of our customers choose to purchase additional boxes, as the shipping costs for separate purchases can make it less economical.
Do I need a Torque Wrench?
To securely lock the carbide inserts, we recommend applying a torque of 48 to 52 Pound-Inches (or 5.42 to 5.88 Newton-Meters). (Note: 1 Newton-Meter is equal to 8.851 Pound-Inches, and 1 Pound-Inch is approximately 0.113 Newton-Meters.) It is crucial not to apply excessive torque, as this could cause the carbide inserts to crack or explode. On the other hand, using too little torque may result in the inserts not being properly secured, which could lead to cracks, shattering, or uneven height on the cutter block, causing ridges or lines on the board.
If one person is responsible for maintaining the machine, they can typically apply the same torque consistently without a torque wrench. However, when multiple people are involved in machine maintenance, ensuring uniform torque application can be challenging. For consistency and peace of mind, we recommend using a torque wrench.
What kind of steel the cutter block is made of?
The cutter block is constructed using GB/T 40Cr, a structural alloy steel of the same caliber as ASTM grade 5140, AISI 5140, SAE 5140, DIN 41Cr4, BS 41Cr4, JIS SCr440, and EN 41Cr4.The primary components of this steel are as follows: carbon (C) at a range of 0.37-0.44%, silicon (Si) between 0.17-0.37%, manganese (Mn) within 0.50-0.80%, and chromium (Cr) from 0.80-1.10%.
In terms of physical properties, this steel exhibits a tensile strength range of 115-234σb/MPa, a yield strength of 2σ 0.2 ≥/MPa, and an elongation capacity of 65 δ5≥ (%). It also has a HBS range of 123-321 and a HRC rating of 30.
This alloy steel is frequently utilized in low to moderately stressed components for machines, engines, and vehicles.
